If AC bisects < BAD, it means it cuts it into 2 equal parts

so < BAC = < CAD

3x + 12 = 5x
12 = 5x - 3x
12 = 2x
12/2 = x
6 = x

< BAC = 3x + 12.......3(6) + 12 = 30 degrees <===

Suppose you had to find 4 x 57. How are the expanded algorithm and the standard algorithm alike? And how are they different?
Nookie1986 [14]
The expanded algorithm is given as follows:

4 x 57 = (4 x 50) + (4 x 7) = 200 + 28 = 228


The standard algorithm is given as follows:

\ \ \ \ \ \ {_2}\\{ \ \ \ \ \ \ 5 \ 7} \\ \times \ \ \ \ \ 4 \\ = \overline{\underline{2\ 2\ 8}}
